Semantic Learning for Analysis of Overlapping LPI Radar Signals [PDF]
IEEE Transactions on Instrumentation and Measurement, 2023 The increasingly complex radio environment may cause the received low probability of intercept (LPI) radar signals to overlap in time-frequency domains. Analyzing overlapping LPI radar signals requires identifying the modulation type and estimating the parameters of each component.

LPI Radar Sinyallerinin Ozimge Yaklasimi ile Siniflandirilmasi Classification of LPI Radar Signals via Eigenimage Approach [PDF]
2007 IEEE 15th Signal Processing and Communications Applications, 2007 Low Probability of Intercept (LPI) Radar signals have the property of wide bandwidth, low peak power to make them difflcult to be detected by Electronic Support Measures (ESM) receivers. In this study, the detection performances of LPI Radar signals with Wigner-Ville Distributions are examined by treating each distribution as an image.

Deep Learning Approach to LPI Radar Recognition [PDF]
2019 IEEE Radar Conference (RadarConf), 2019 In this study, an advanced automatic low probability of intercept (LPI) radar recognition technique (LWRT) that includes both LPI radar signal classification and parameter extraction is proposed. It is shown with Monte Carlo simulation that, even without the unrealistic assumptions used in the previous studies, the proposed LWRT achieves classification

Methods for Analysis of LPI Radar Signals [PDF]
2006 IEEE 14th Signal Processing and Communications Applications, 2006 LPI (Low Probability of Intercept) radars occupy wide frequency bands and have very low peak power so they are difficult to be detected by hostile intercept receivers. Hostile radiometric receivers are not able to intercept and measure the parameters of LPI signals which lie in wide frequency bands.

Automatic Intrapulse Modulation Classification of Advanced LPI Radar Waveforms
IEEE Transactions on Aerospace and Electronic Systems, 2017In this paper, improved signal processing techniques are developed for the analysis and classification of low probability of intercept (LPI) radar waveforms. The intercepted LPI radar signals are classified based on the type of pulse compression waveform.

Anti-Jamming and LPI Radar with Spread Spectrum Technology [PDF]
Advanced Materials Research, 2011 In order to enhance the capability of anti-jamming and Low Probability of Intercept (LPI) of radar system, spread spectrum signals are designed for modern radar system. Emission signal is coded with PN codes at the transmitting terminal. Spectrum of signal is spreaded and multi-signal mixed together, so it is not easy to intercept.
